---

AKA: Black Brant 11. Status: Active. First Launch: 1990-02-01. Last Launch: 2012-07-23. Number: 8 . Gross mass: 5,300 kg (11,600 lb). Height: 17.00 m (55.00 ft). Diameter: 0.76 m (2.49 ft). Apogee: 1,400 km (800 mi).

The Black Brant XI rocket system was a three stage system used primarily to carry heavy payloads to high altitudes. Its development was a spin-off of the Black Brant XII development. The first and second stages were the Mk 11 Mod 5 Talos rocket motor and the Taurus motor. The third stage was a modified Black Brant VC motor. The Black Brant nozzle was extended for exoatmospheric use and the tail cone was changed to enclose the nozzle. The aft end of the tail cone had a restraining device to keep the Taurus and Black Brant connected during second stage coasting. This motor configuration made up the first three stages of the Black Brant XII.

The standard payload configuration for the Black Brant XI vehicle was 0.44 cm in diameter with a 3:1 ogive nose shape.
